I Original application filed May 10, 1910, Serial No. 560,44}. Divided and this application filed June 5, 1911.

- Serial No. 631.421.

To aZZxw/wm it may concern.

' Beit known that I, SAMUEL E. CARLIX. a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Calculating-Machines, ofiiwhich the following is a specification.

This application is a division of my application Serial NumberfiGOA H filed in the United States Patent Oflice 'on or about May 10th, 1910.,and to which application reference may be hadfor an understanding oil -the parts not specifically described herein.

More particularly the present invention relates to an improved machine of this class having means for returning the typewriter carriage to its initial or starting position from any point of its advancement, and also means for preventing accidental or mischievous operation of the advancing mechanism for the typewriter carriage simultaneously with the operation otthe returning mechanism for the iarriage to prevent looking of the parts and the consequent damage resulting therefrom. v

A further object of the present invention is to provide an improved machine of this character having means for returning the typewriter carriage to any predetermined point intermediate the point to which it has been advanced and the initial or starting position. at the will of the operator so that the typewriter carriage will he properly and quickly positioned for tabulating the amounts on sheets of paper.

A. further object of this invention is to provide an improved machine of this class in which the numeral keys may lie alternatively used to perform their usual functions, such as'printing digits, or an added function, such as tabulating the carriage backwardly or forwardly predetermined amounts corresponding to the values of the numeral key actuated.

A further object is to provide an improved macl'iine of this class which will be simple, durable and cheap in construction and effective and etlicient in operation.

To the attainment of these ends and the accomplishment of other new and useful Oi)- jects. as will a ppear. the invention consists in the features of l'lffvitliy in substantially the co combination and arran nn-nt embodiment of the mg movements of the carriage. Fig. 2 is a I skeleton view in vertical section taken from front to rear, showing the connection from i the supplementary numeral keys to the typewriter numeral keys. and the means for intel-rupture,- this connection when the supple mentary numeral keys are used to traverse the carriage backward predetermined variable amounts. In this figure, the supplementary numeral key 82 therein represented is assumed to be in its depressed position. Fig. 3 is a detail view in top plan of the means for locking the remaining supplementary numeral keys after one has been actuated. Fig. i is a fragmentary vertical sectioirsliowing details of the parts shown in Fig. looking; from left to right of Fig. 2. Fig. 5 is a fragmentary horizontal section of the means for driving the carriage backiiard one. two. three. four, etc. steps, according to the particular key actuated. Fig. 6 is a vertical section showing the driving motor and certain connections thereto. Fig. 7 is a skeleton vertical section showing the means for returning the carriage to its normal starting position from any point in its advancement. in this figure the carriage-r'et-urniir; key 123 is shown in its normal or elevated position, but the position of the link 196 is that which it assumes upon the actuation of the clutch-shifting key 165. Fig. 8 is a fragmentary vertical section showing on a smaller scale. the connections from the mechanism illustrated in Fig. T. to the .-pewriter carriage. The lever 127 is here shown in its initial position. Fig. 5) isa detail of the. riutch and key for operating the same, which connects the variable-step driving mechanism to the carriage. Fig. 10 is a view oi the parts shown in Fig '9, taken at right angles thereto. the said. parts being in normal position. Fig. 1.1 is a vertical section of certain. of the parts shown in Figs. 9 and it). taken at right angles to Fig. 10, and from the opposite side to Fig. 9. Fig. 12 a detail view in side elevation of the ciutch. shown in Figs. 9 to 1'1. Big. 13 is a face view of the bevel gear shown in Figs.

9 to it, and illustrating thc cluf-h openings by which the clutch pins illustrated in Fig. 12 enable the drive of the bev l gear from the shall; on which it is loosely mounted.

motor 58 (see Figs. 1, and 3) is provided for imparting motion to the parts and this motor inthe present exemplilication of the invention is shownas a spring motor which is provided with a gear 55) on its periphery and thisnear 59 meshes with a gear to n a shaft, (31, which is journaled in suilable supports 6!. This shaft 61 is adaph l to impart a variable degree of rotation to a shatl l 2 3. which latter is arranged adjacent the shall. 31. ano preferably in advance thereof. Secured to the shaft 63 and for rotation therewith are a series of gears b-land selector mechanisms may be provided for controlling the degree of rotation of the Shaft (33.

Any number of these selector mechanisms may be provided but in the present exemplilication ot' the invention nine are employed, one for each of the nine numeral lteys 65 of the typewriter (oi-res ionding in values from l to "fi." The. construction and operation ot each of these selector mechanisms are the same and therefore the specific description of one will. apply equally as well to them all. They each comprise a sleeve (H3. which is mounted upon the shaft 61 for rotation therewith and for sliding adj-L st ment hmgitudinally on the shaftsee. Fi'gs. l and. 5) and the sleeve is provided with peripheral spaced ribs (37. A one-toothed gear 8 is secured to the sleeve (36 and a mutilated gear (35) is also secured to the sleeve. The mutilated gears i are provided with a dil'l'erent number of teeth, that is to say, each of the mutilated gears is provided with a number of teeth corresponding to the nnmber oi the numeral key (35 of the typewriter. to which it is connected, as ill be understood. An upright sleeve is rotatably mounted in a suitable support Tl and is provided with a gear portion 72 (see Fi 4) which meshes with the ribs (37 on the sleeve on. .\n elastic member 73 is convnected to an. extension '74- on the sleeve by one extremit and anchored as at T5 to a fixed support. The tendency of this elastic member 73 is to normally rotate the sleeve 70 and the near 72 so as to move the sleeve. ilil on the shait l to a position to bring the corresponding gear (if) in mesh with the gear (34-.

The sleeve is adjusted on the st aft til. to more the gear so out of actuating position with respect to the gear (is by means of an arm Tb which connected to a root. shaft 77 and this arm engages a projection 78 on the sleeve i l to rotate the sleeve and the gear '72 in the opposite direction against the tension of the ela 1 member 73 when the shaft; 77 is rocked, in direction. inc

gear 69 is locked in its non-meshing or in operating position by means of a stem 79 which is provided with a pin 80 normallv seated in a slot 81 in the.- slecvo 70 and adapted to be moved out ot the slot when the stem is raised. Actuating or numeral keys are provided for shitting the stems 79 and these keys are each connected to a lever or arm 83 which is pivotally supported intermediate its ends as at El and one e. trcmity is pivotally connected as at 8-3 to the stem of the key 82. The. stem 79 is pivotally connected as at 86 to the other end at the arm at a point remote from the extrcnr ity of the arm. An elastic member 87 is provided which tends normally to restore. the key and to move the stem Tl) in a direction to cause the pin 80 to enter the slot 81 in the sleeve 70.

it will thus be seen that when any one ot v I A V y the gears b 15 slniteil by the (,iperation oil the corresponding; ltey 82. the shaft ()8 will be rotated a number of steps of rotation vided with extremities S9, 90, projecting to-' ward each other and these extremities are adapted to engage 'i -ojecting pins or lugs fl]. (see Fig. 1S and which are also diag ammatically illustrated in Fig. 7L and these escapement members 87, 88 are mounted for movement about a pivot 92. A. link 93 is connected at one extremity to the escapeinent to rock it about its pivot 92 and at its other extremity to a dog M, which is secured intermediate its ends to a rock shaft 95. Secured also to the rock shaft 95 is a series of (ions or fingers 96, one for each ot the arms or levers 83, and the tree extremity of each of these dogs or lingers projects into the path oi? movement of a projection 97 on the extremity of the ,-.orrcspondina arm or lever 83 adjacent the point of pivotal connection 86 of the stem with the arm 83 so that when the latter is rocked by means of the key 82 to shift the stem 79 to release the mutilated gear (39 and thereby permit the latter to be adjusted into operating position with respect to the gear til the shaft 95 will also be rocked, the parts being so timed that the gear on will assume. an operating position before the shaft as is rocked. As the shaft 95 is rocked, the escaiiiementarms 87, 88, will be rocked about their point 0t pivotal. support to release the motor 58 and when thus released the motor will make one step oi rotation.

The connection between the motor and the shaft (51 is so proportioned that on each step of rotation of the motor will make one complete rotation and at the the shaft til completion of this movement, the shaft 77 and its arm 76 will 'be rocked to shift the gear 69 from its previous active position in mesh with gear 64, to its inactive position on the shaft 61 in which it is released from said gear 64. Cams or projections 105 are also secured to the shaft .61 and are adapted to engage arms 106 which latter are secured the sleeve to receive the pin or projection- 80 on the'stem 79.

in order to lock the remaining keys 82 against actuation when on '2 of the said keys 1 has been actuated, a locking plate or member 107 is provided and is supported by the arms 101-, loosely mounted on shaft 77. When shaft 61 is rotated, cams 100 thereon will engage and rock arms 101, and thus bring locking plate 107 into play (see Figs. 1, .2, 4 and 6). This locking plate is provided with recesses adapted to stand astride of the stems 79 and a pin 108 similar to the pin 80 is provided on each of the stems and spaced from the pin 80 so that the plate will pass therebetween, as shown in Fig. to lock the keys against actuation.

When any one of the keys 82 has been actuated the stem 79 will be shifted so as to move the pin or projection 108 to a position above the plate 107 so that when the latter is actuated it will pass below the pin 108' and lock this key in an actuated position while at the same time the remaining keys will be locked against actuation by the plate 107 passing above the pins 108 on the stems 79 corresponding thereto.

As the selector-mechanisms which include thegears 69 are rendered active by the keys 82in the manner already set forth, the cor responding keys 65 of the typewriter will beactuated by means of the onetoothed gears 68, the tooth of each of which latter is adapted to engage the extremity 119 of an ,arm or lever 120 which is pivotally supported intermediate its ends as at 121 so that the extremity 119 will project into the path of movement of the tooth on the gear 68. The other extremity of this arm or lever is connected by means'of a connection 122 to the respective key 65 so as to operate the latter against the tension of a spring 185.

After the carriage 109 of the typewriter has been advanced, it may be returned from any position to which it has beenadvanced to its original or starting position by means of a key 123, (see Figs. 1 and 7) which key operates an arm or lever 124 pivotally supported intermediate its ends as at .125, and one extremity of this aim or lever is provided with a projection 126, into the path of movement of which the dog 94 projects so that when the key 123 is depressed the escapement arms 87*, 88, will be rocked in a manner similar to that already described to release the motor 58.

As the typewriter carriage 109 is advanced step-by-step in the ordinary and usual manner under the influence of the ordinary typewriter escapement and ordinary sprin drum, (not shown), by the operation of the keys 65 thereof or by the keys 82, this advancing movement will'be communicated to an arm or lever 127 '(see' particularly Figs. 1, 7 and 8) which is pivotally supported i ntermediate its ends as at 128 to a suitable si'ipport 129 on the base 22. The power of the spring drum or barrel just mentioned is, however, less than that of the motor 58. One extremity of this arm or lever 127 is provided with a toothed segment 130 which meshes with a gear 131 and to which gear is secured a gear 132. This latter gear 132 meshes with a gear 133 on the shaft 134 and this shaft 134 receives its motion through the medium of intermeshing gears 135, 136, the gear 136 being secured to an upright shaft 137. The shaft 137 receives its motion from the gear 111, which meshes with a gear 138 on the shaft 137. The other end 1390f the arm or lever 127 is adapted to he moved toward a cam 140 which is loosely mounted on the shaft 61. This cam 140is secured to a disk 141 which is also loosely mounted on the shaft 61 and clutch mechanism is provided for locking the cam 140 for rotation with the shaft 61.

key 123 when the latter is depressed to rock the escapement arms 87, 88. In .order to accomplish this result there is provided a second dog 145 which is pivoted to a fixed support 146 and one extremity is adapted to engage a shoulder 147 on the dog 143 to move the latter out of engagement with the star or toothed wheel 142 and against the tension of the elastic member 144. The other end of the dog 145 is connected by means of a link 148 to the arm or lever .124. Thus it will be seen that when the key 123 is depressed to move the dog 145 from the position shown in Fig. 7 and out of engagement with the dog143, the latter will be released and the elastic member will move it into engagement with the star or toothed wheel 142 to lock the disk 14]. and cam 140.

for rotation with the shaft. The extremity A;

1300f the arm or lever 127 will be moved toward the cam 1&0 a distance corresponding to the extent of the advancing movement of the carriage 109 of the typewriter so that when the my 123 is depressed and the cam 110 rotated with the shaft 61, the cam will engage the extremity 139 of the arm or lever 127,, thereby raising or moving the end 130 in the opposite direction which will reverse the direction of rotation of the shaft 137 to move the carriage 109 back to the initial or starting position. \Vhen the key 123 is released the dog 113 will be automatically shifted by the dog 115 to release the clutch mechanism.

It is the intention of the present application to provide means whereby the typewriter carriage may be returned to its initial or starting position from any point of its advancement and also to provide means wl'iereby the typewriter carriage may be returned to any point between the point to which. it has been advanced and its initial or starting position so as to tabulate the amounts, at the will of the operator, and also to utilize the selector mechanisms which impart a variable movement to the shaft 63, for thus returning the typewriter carrlage to the intcrnu'diate positions. In order to accomplish this and also to prevent the operation of the ty iiewriter keys 65 during this return 1110\llll0l1t of the typewriter carriage, meel-iairism must be provided. for shifting the arms or levers so that the extremities 11$) thereof will be moved out of the path of nuivement of the tooth on the onetoothed gears 58. complishin r these results will now be de scribed.- The gear 152 (see particularly Figs. 1 and 10110 13 inclusive) is mounted loosely upon the shaft 63. A gear 157 is also loosely mounted on the shaft 63 and spaced from the gear 152. The adjacent faces of the gears 152, 157, are provided with a plurality of apertures 158, and a clutch member or collar is mounted upon the shaft (33 between the gears 152, 157. This clutch member or collar is keyed to the shaft (53 for rotation therewith and is ad apted to be shifted on the shaft longitudinally thereof and toward and away from each of the gears 152 157. l. rojecting laterally from each face of the clutch member 155) are spaced pins or projections 100 which are adapted to enter the apertures 158 in the respective gears 157. These gears are spaced from each other a suliicient distance to permit the clutch member 159 to be shifted to such a position that when the pins or projections 150 on one face enter 'the aperti'ires 158 on the respective gears 152, 157, the pins or pro ections 160 on the' opposite face will be disconnected from the respective gears or moved out of the recesses therein, so that when one of the gears The mechanisms for ac is locked for rotation with the shaft 63, the other is free to rotate thereon. The clutch member 159 is adapted to be shifted by means of a key through the intermediary of a bell crank lever 161, one arm of which is formed into a yoke havin projections adapted to enter a circumferential groove or slot in the periphery of the clutch member in the ordinary and well known manner. The other arm of the bell crank lever is connected by means of a pin and slot connection 162, 163, with the stem 161 of the key 165 and the slot 163 is preferably so arranged that when the key 165 is depressed the bell crank lever 161 will move the clutch member 159 to lock the gear 157 to the shaft 63; An elastic member 166 such as a coil spring or the like, is provided,

one end of which-is connected to the yoke arm of the bell crank lever and the other end is anchored to a suitable fixed support and tends normally to shift the bell crank lever 161 to more the clutch member 159 to lock the gear 152 to theshaft 03. Thus it will be seen that when the key 105 is depressed. the gear 157 will be locked to the shaft (33 so that the motion of the shaft will be communicated to the typewriter arriage 101), through the medium of agent: 16? which meshes with the gear 157 and which gear 167 is secured to a shaftlGS extending to the rear of the machine. 011 the shaft 168 is a gear 169 which meshes with a gear 170 on the shaft 13. and which imparts rotation to the shaft 131 in a direction opposed to the direction of rotation 'iniparted to the shaft- 131 by the :ulvancing' movement of the typewriter carriage. the clutch men'ibcr 155) is shifted to loch the gear 157 to the shaft 08, the key 165 is employed for shifting the arms or levers 120 into an inactive position sothat the extremities 119 thereof will be moved out of the path of movement of the tooth of the one-toothed gear 68. This may be accomplished in the following manner: The stem 161 of the key 1135 is of some length and is provided witlrrack teeth 173 which mesh with a. toothed (.ylllltlel. or barrel 1-71 rotatably mounted in suitable supports 175 and arranged at right angles to the stem 161. Secured to and for rotation with the cylinder or barrel 17-1. is a gear 170 which meshes with the gear 177 on a shaft 178 see particularly Figs. 1, 2, 3, 5, 11 and 13). This shaft 178 is journal ed in a suitable bearing 179 and the supports 62 and is provii'led with a crank arm 180. Loosely mounted upon a suitable support. preferably the shaft 121, are arms 182 which are connected by a cross bar or rod 183. This bar or rod is arranged above and projects across the arms 120 forward of the pivot thereof and the arm 182 is connected to one of the arms 180 by means of a 35 p f therefore to obviate this difiiculty and to prelink or connection 184 so that when the key 165 is depressed, the cylinder .or barrel 174 will be rotated and this rotary motion willbe imparted'to theshaft 17 8 to move the arm 180 thereon downwardly. This movement of the arm 180 will draw the bar or rod 183 into engagement with the extremities of the arms l2o todepress the latter to move them out of the path of movement of the tooth of the one-toothed gears 68. These parts will beheldin this pdsition .as long as the key 165 is held depressed, but when the key is released, the elastic member 166 will return the key and at the same time will shift the clutch member 159 to unlock the gear 157 and lock the gear 152 and the return movement of the key will also raise the arm 180 to elevate the bar or rod 183 to permit the extremities 119 of the arms '120 to rerase'um'e positions in the path of movement ofthe tooth on the gears 68.

Should it happen that oneofthe keys 82 is accidentally depressed or mis'chievously actuated at the same time that it is desired i H or starting position by the actuation of the key 123, itwill beapparent that the keyto return the typewriter'carriage to its initial 65 of'the typewriter, corresponding to the V key 82 which. has been accidentally actuated, '30

would be operated and this would tend to cause the typewriteficarriage to advance,-

while the-actuation {of the key .123 would tend to move the. carriage in the opposite di- ,rection, thereby locking the parts which might result in serious damage. In order vent the locking of the parts mechanism is provided whereby the actuation of the key the teeth of the one-toothed .gears 68 and therebyrender the advancing mechanism of the typewriter carriage inactive, even though 1 bothof said keys are simultaneously actuated. Suitable mechanisms for accomplishing this result will nowbe described, reference be- 'ing had particularly to Figs. 4, 5'and 7. Se-

cured'to the-shaft 17 8 is an arm 195, connected to which, at one extremity, is a link 196. Theo'ther extremity of the link is provided with-a slot 197 and this extremity of the links is connected to an extension 198-on the form a loose connection. When the key 123 is depressed, the pin 199-will engage the end of the slot 197 in the link 196 to rock the shaft 178 in a direction to lower the bar or rod 183 into engagement with the extremities 119 of the arms or levers 120 to depress the latter and hold them depressed until the key 123 is released. This pin and slot connection between the'link 196 and the arm or lever 124 permits the-shaft 178 to be rocked by the one-toothed gears 68 when they engage the extremities 119 of the arms or levers 120 and when theshaft 178 is thus levers 120 through the medium of the onetoothed gears 68.

' In the operation of the device during the "advancing movement or the carriage 109, the shaft 134will be rotated, and this will in turn "rotate the gears 132,- 131, to move the arm 127 about its pivot so that the free extremity thereof will be moved toward the cam 140. When it is desiredto return the typewriter carriage to its original or starting position from any point to which it has been advanced, the key 123 is actuated and'this key will lock the cam 140 for rotation with the shaft 61, at the same time the escapement arms 87, 88, will be rocked to release the motor 58 to permit it to make one step of rotation. With the parts in this position, the rotation of the shaft 61 will rotate the cam 140, which latter will (angage the extremity of the arm 127 to move it in the opposite direction, which movement will impart a reverse rotary movement to the shaft 134 and the typewriter carriage will be thus returned. When the key 123 is actuated, the bar or member 183 will be depressed to move the extremities 119 'of the arms or levers 120 out of the path of movement of the teeth of the one-toothed gears 68 to prevent the actuation of the keys 65 of the typewriter proper. in the event one of the keys of the series 82 has been accidentally actuated. When it is desired to return the typewriter carriage 109 to a predetermined point intermediate the initial or starting point and the point to which it has been ad vanced by the employment of the selector mechanisms and which mechanisms impart a variable motion to the shaft 63, the key 165 is actuated to unlock the gear 152 from the shaft 63 and to lock the gear 157 to the shaft 63. At the same time the bar or rod 183 will be depressed to move the extremities 119 of the arms 120 out of the paths'of movement of the one-toothed gears 68. 'Withthe parts thus adjusted, the key'of the series82, corresponding to the number of spaces it is desired to return the carriage 109, is actuated. The actuation of this key will render I release the motor 58, thereby permitting the latter to move one step of rotation. This rotary motion of the motor will be imparted to the shaft 53 through the medium of the gear 64 which meshes with the mutilated gear 69 that has been locked to the shaft 61..

"During this operation the key 165 must be held depressed and when thus held, the variable motion of the shaft 63 will be imparted to the shaft 134 through the medium of the gears 157, 167, shaft 168 and gears 169, 170, to rotate the shaft 134 in a directic-n to return the carriage 109 a number of steps equal to the number of steps of rotation imparted to'the shaft 63. After the typewriter carriage has been thus returned, the gear 69 which has been lockedto the shaft 61 will be automatically released or rendered inactive and the'key 82 returned in the manner as fully set forth in the application above referred to. When the key 165 is released, the gear 157 will be unlocked from the shaft 63. The bar or rod 183 will be elevated so as to permitthe extremities 119 of the arms or levers 120 to move to such positions that any one of them may be actuated to operate the corresponding keys 65 of the typewriter when one of the mutilated gears 69 is rendered active by the operation of the respective keys 82.
